Precautions
Minimizing Possible Risks: Training may include some
risk. Before beginning a regular training program, answer
the following questions concerning your health status. If
you answer yes to any of these questions, consult a
physician before starting any training program.
• Have you been physically inactive for the past 5 years?
• Do you have high blood pressure or high blood
cholesterol?
• Do you have symptoms of any disease?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Are you recovering from a serious illness or medical
treatment?
• Do you use a pacemaker or other implanted electronic
device?
• Do you smoke?
• Are you pregnant?
Note that in addition to training intensity, medications for
heart conditions, blood pressure, psychological conditions,
asthma, breathing, etc., as well as some energy drinks,
alcohol, and nicotine may also affect heart rate.
It is important to be sensitive to your body’s responses
during training. If you feel unexpected pain or excessive
fatigue when training, stop the training session or
continue at a lighter intensity.
If you have a pacemaker, defibrillator or other implanted
electronic device, you use the Polar RS300X at your own
risk. Before starting use, take a maximal training stress
test under the supervision of a physician. The test is to
ensure the safety and reliability of the simultaneous use of
the pacemaker and the Polar RS300X.
If you are allergic to any substance that comes into
contact with your skin or if you suspect an allergic
reaction due to using the product, check the listed
materials in Technical Specifications. To avoid any skin
reaction to the transmitter, wear it over a shirt. Moisten
the shirt well under the electrodes to ensure flawless
operation. If you use insect repellent on your skin, make
sure that it does not come into contact with the
transmitter.
